This simple microcontroller programmer can progam most of the 89 like Atmel'sAT89S51, AT89S52, AT89S53, AT89S8252, AT89S8253 including the Atmel AVR series of microcontroller , it does not support 89C series . It simply consists of an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.Features

Works under multiple platforms. Linux, Mac OS X and Windows are tested.

No special controllers or smd components are needed.

Programming speed is up to 5kBytes/sec.

SCK option to support targets with low clock speed (< 1,5MHz).

if you have all ready have your USBasp programmer, which is previously posted on my blog as USB AVR PROGRAMMER then there is no need build new hardware you just need to change the firmware of the programmer microcontroller.

Simple Steps to made This programmerStep 1:-Step 1:-

Download:Firmware and circuit
The following packages include circuit and firmware.
Firmware is the software which going to be burn into programmer's microcontroller, this firmware have code to enable the programmer to communicate with pc via usb and target microcontroller
